BERTHOLD HUBER, OF TAUNTON, MASSACHUSETTS, ASSIGNOB TO THE HUBERPRINTING PRESS COMPANY, OF SAME PLACE.

PRINTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 350,056, datedSeptember 28, 1886.

Application filed September 29, 1884. Serial No. 144,220.

To all whom it may concern Be it known that I, BERTHOLD HUBER, a citizenof the United States, residing at Taunton, in the county of Bristol andState of Massachusetts, have invented a new and useful Printing-Machine,of which the following is a specification.

The object of my present invention is the production of a printing-pressespecially adapted for printing from sheet metal or from stereotype,electrotype, and zincographic plates.

My invention relates to a printing-press in which the impressions aregiven by the employment of two cylinders, upon one of which is securedthe form, the other being fitted with grippers in the usual manner. Y

it also relates to that class of presses in which water and ink are usedalternately in the process of printing. In all such former constructionsthat part of the type-cylinder not used for the form was employed as aninking surface or table, onto which the ink was deposited from thefountain, and from which it was delivered onto the form-rollers. Theinking surface or table of presses heretofore employed being type-high,or in the same circumferential line with the type, it was necessary tolift the water-rollers away from the form-cylinder at every revolutionof the latter, and therefore it was impossible to drive the waterrollersby gears at the same positive speed as that of the surface-speed of thecylinder.

The object of my invention is to drive the water-rollers as well as theink'rollers by the same means, and to give both sets of rollers apositive surface-speed.

In this my invention the surface of the formcylinder other than thatoccupied by the form is disposed below that portion occupied by saidform, while the water-rollers,having a surfacespeed equal to that of theform-cylinder, are provided with positive gear mechanism, and arearranged in the circumferential line or printing-line of that portion ofthe formcylinder occupied by the form, so that in the revolution of theformcylinder the said water-rollers travel over the surface of the formplaced on said cylinder, while they do not touch the depressed surfaceof said for1n-cyl- 5o inder. Furthermore, the ink-rollers are in (Nomodel.)

fixed relation with the form-cylinder, and by reason of the depressedportion, said cylinder comes in contact only with the form placed on theraised or normally high portion of said cylinder. By this arrangementthe water and ink rollers in the revolution of the form-cylinderalternately pass over the face of the form or plate placed on thenormally high portion of said cylinder, but do not touch any portion ofsaid cylindenas is done in the common form of printing-presses, whereina portion of the surface of the cylinder serves as an inking-table.Furthermore, the inking apparatus and the cylinder have their drivingmechanism connected to and operated by a common shaft, which is inconstant engagement with the driving mechanism for the ink apparatus,while it has merely a clutch-connection with the mechanism for thecylinders. The object to be attained by this construction is to permitthe inking apparatus to be driven independently of the cylinders, so asto enable an operator to ink up the inkapparatus without inking theform-an operationvery essential to the class of presses to which myinvention belongs. Furthermore,the inking apparatus is located above theformcylinder, so as to permit an operator to stand at the back of saidcylinder to adjust the zinc plate thereon, or to remove said platetherefrom and substitute another when desired, while the waterrollersare placed beneath the formcylinder.

'lheinvention consists in certain novel combinations and arrangemeuts,ashereinafter particularly set forth and claimed.

Figure l is a vertical section of a machine embodying my invention. Fig.2 is a vertical cross-section on the line as 00, Fig. 1. Fig. 3 is aplan view of the cylinders and principal gears, the frame-work beingomitted. Fig. 4 is a detail to be referred to. Fig. 5 shows details ofthe clutch mechanism on the drivingshaft, such clutch mechanism being ofcommon construction.

The two side frames, A A and the foundation B constitute the frame-work.

G is the forin'cylinder, onto the high part c of which is fastened thezinc plate, which is bent at a right angle on the forward end and heldin place by the nippers a, the tail end Ice ' which meshes into the gearH, loose on a j ourshaft F outside of the frame A proper position on thepaper.

being drawn and fastened by a number of clamps, 0 The opposite side, 0",of the cylinder 0 is out below the printing-line, so that in itsrotation it will not come in contact with either the form-rollers orwater-rollers.

O is the impression-cylinder, and is fitted with grippers c in the usualmanner.

In the accompanying drawings the impression and type cylinders are ofthe same diameter, which, however, is not essential, as theirproportions might be two to one.

C is the delivery'cylinder, and is fitted with grippers c. p

D is the fly, and Ethe feed-board.

F is the driving-shaft, journaled in the two.- frames A A.

F represents a tight and loose pulley on the Inside, and nearest theframe A is a pinion, G, fitting loosely on the shaft F, but capable ofbeing fastened firmly to said shaft by the clutch F". By sliding thepinion G toward the frame A it is released from the clutch F, and theshaft F is allowed to revolve without imparting motion to the pinion G.The pinion G engages the pinion G, which is secured to the cylinder 0 byscrew-bolts 2,passing through slots 0' in the gear G, to allow therelative position of the gear G and the cylinder 0 to be changed, so asto bring the head-line of the form in its The gear G engages the gear G,which is fastened to the cylinder 0, and this latter gear, G engages anddrives the deliverycylindergear G which is fastened to the therefore beseen into the clutch F delivery-cylinder 0 It will if the pinion G isthrown then the rotation of the shaft F will drive the train of gears G,G, and G with their attached cylinders O, OflandG. If the pinion G isthrown out ofthe clutch F, then the rotation of the shaft F will not betransmitted to the said train of gears and their attached cylinders.

Fastened on the driving-shaft F, near itsopposite end, (see Fig. 3,) isanother pinion, H,

. nal of the cylinder-shalt, and free to rotate gear H meshes in turnengaging the gear h thereon without moving the cylinder 0. The into thethree intermediate gears, H (shown in dotted lines in Fig. 1, and insection in Fig. 4,) said gears H on and driving the dis tributer orvibrator rollers H for the ink, and also the water-distribution roller 0in like manner. The gear H also drives the inter mediate gear, H whichmeshes into the gear H, (see Fig. 2,) which is fastened to the ink-"drum I, upon which rest four small rollers,k. The ink is transmittedfrom the ink-fountain L to the ink-drum I by the roller 75, whichoscillates between the said ink-fountain and ink-drum around the shaftPin usual manner. From the ink-drum I the ink is conducted to and thedistributer or vibrator rollers H, as stated before, receive a posiwhichlatter,

having a form-surface face below the level of the form-surface, as

tive motionfrom the cylinder'G through two of the intermediate gears, H.

On the outside of the frame A and fastened is a pinion, p, (see. gearp", fastened tori l;-

and the gear 11 0, which oscillates between the fountain-r011. o and thedistributer-roll 0 around the shaft 0. The water-distributer roll 0 andthe water, form-rollers o are journaled in the arms 0", the upper endsof which are hinged on the studs 0, While their lowerends rest on the cocentric-shaft 0 The position of the arms 0", as shown in thedrawings,will keep the waterrollers close to the cylinder, and in whatmight be called the working position, while, upon reversing theeccentric-shaft o the arms" 0 will be lowered to throw the gear Hflwhich engages the distributer-roll 0*,out'of gear with the gear H makeit convenient to removethe water formrollers from contact with theform-cylinder. By

bringing the cylinder 0 intothe positionwhere' the type-surface 0 willbe located between the water-rollers 0 and the first form-roller at theback side of the machine and then sliding the pinion G out of the clutchF on the shaft F the machine is then in the most con venient positionfor inking up.

Upon putting the machine in motion the cylinders O O O -will remainstationary, but the inking apparatus will be in motion, and thedistribution of ink and'water may be adjusted and regulated ready forprinting. Did the form-rollers depend upon an inking surface or table onthe cylinder 0', then the motion of the cylinder 0 would be necessaryduring the operation of inking up, and the impression -cylinder 0 wouldhave to be separated from the form-cylinder G. On the other hand, byusing instead of an inking surface or table in the form-cylinderaseparateink-drum,

I, I obtain the advantage of running the ink.

and water apparatus independently of the cylinders, and also theadvantage of driving the water-rollers in a positive manner, therebysecuring a more even damping.
